Description

Technical Field

[0001] This invention relates to the field of traffic light installation, and in particular to a method for constructing an L-shaped traffic light. Background Technology

[0002] With the increasing density of urban traffic networks, L-shaped traffic lights are becoming more widely used as an important facility for coordinated management of multiple intersections. Due to the special structure of L-shaped traffic lights, their horizontal and vertical bars are integrated, resulting in uneven distribution of the center of gravity and large individual weight, which presents many technical challenges during installation and construction.

[0003] Currently, the construction of traditional L-shaped traffic lights relies heavily on large cranes in conjunction with manual labor for hoisting, tilting, and positioning. This involves lifting the light from a transport vehicle using a large crane, followed by installation and fixation. This traditional method suffers from slow construction speed, low efficiency, significant safety hazards, large lane occupation, and difficulty in ensuring the verticality and flatness of the traffic lights. Furthermore, the large weight of the cranes makes them difficult to move and hinders short-distance material transport. Large cranes also struggle to achieve millimeter-level precision adjustments, often requiring repeated adjustments due to inaccurate positioning when aligning the traffic light with the mounting base. This is not only time-consuming and labor-intensive but can also damage the equipment structure. The numerous high-altitude operations and heavy reliance on manual labor, coupled with unstable hoisting posture control in complex intersection environments, can easily lead to safety accidents.

[0004] Therefore, developing a construction method and device for L-shaped traffic lights that enables multi-component collaborative operation and high-precision positioning has become an urgent technical problem to be solved in this field. Summary of the Invention

[0005] The main objective of this invention is to provide an L-shaped traffic light construction method, which solves the problem that existing large cranes are unable to achieve millimeter-level fine adjustments, and that repeated adjustments are often required when the traffic light is connected to the mounting base due to inaccurate positioning.

Restart the rotating component in the docking device to rotate the L-shaped traffic light from a horizontal position to a vertical position, and then drive the docking device to the required installation position. S6. Restart lifting assembly one and lifting assembly two to slowly lower the height of the L-shaped traffic light from the ground mounting base. Lifting assembly one makes coarse adjustments and lifting assembly two makes fine adjustments so that the bottom of the L-shaped traffic light finally fits the mounting base. S7. After locking the L-shaped traffic light to the mounting base, activate the clamping assembly to release the vertical rod of the L-shaped traffic light, completing the installation here. S8.

Step S6.2: After the construction personnel confirm the alignment, the lifting component 1 2 is coarsely adjusted and the lifting component 2 3 is finely adjusted so that the bottom of the L-shaped traffic light 8 finally fits the mounting base, thus completing the installation.

[0027] Example 2 Further explanation in conjunction with Example 1, such as Figure 1-9 The structure shown illustrates a method for constructing an L-shaped traffic light, which includes the following steps: The S1.1 master control module 203 controls the drive wheels 102 to drive the frame assembly 1, so that the entire docking device 10 follows the transport vehicle 7 to the intersection where construction is required.

[0028] S1.2 The transport vehicle 7 is used to transport the L-shaped traffic light 8. A sleeper 9 is placed between the L-shaped traffic light 8 and the floor of the transport vehicle 7. The sleeper 9 is used to raise the L-shaped traffic light 8, providing sufficient operating space for the subsequent hoisting component 6 to grip the steel cable 610, which is convenient for quick grabbing.

[0029] The S2.1 master control module 203 sends a command to the tilting motor 602, which drives the tilting arm 603 to tilt around the tilting support 601, so as to precisely adjust the hoisting top plate 604 directly above the L-shaped traffic light 8.

[0030] The S2.2 main control module 203 controls the winch 304 to tighten the traction cable 307, assisting in maintaining the stability of the tilting boom 603; Subsequently, the winch 2 605 was controlled to lower the hoisting steel cable 610. Under the visual monitoring of the main control module, the construction personnel firmly tied the hoisting steel cable 610 to the vertical pole of the L-shaped traffic light 8.

[0031] S2.3 main control module 203 starts winch 605, which lifts L-shaped traffic light 8 to a preset height via hoisting steel cable 610. This height is designed to avoid touching the transport vehicle 7 and to facilitate subsequent clamping by clamping component 5.

[0032] S3.1 The main control module 203 controls the lifting cylinder 205 of the lifting component 2 to perform initial lifting and lowering, adjusting the clamping component 5 to the approximate height; Then, the lifting motor 309 of the second lifting component 3 drives the lifting screw 310 for precise fine-tuning, so that the axis of the clamping bracket 502 is aligned with the center line of the vertical pole of the L-shaped traffic light 8.

[0033] The S3.2 main control module 203 controls the telescopic electric cylinder 501 to push the clamping bracket 502 forward, so as to introduce the vertical rod of the L-shaped traffic light 8 into the V-shaped groove 505 inside the clamping bracket 502.

[0034] The S3.3 main control module 203 synchronously starts the clamping cylinder 503, driving the two clamping seats 504 to move towards each other, using the clamping seats 504 made of hard rubber to firmly clamp the vertical rod of the L-shaped traffic light 8.

[0035] The V-groove 505 ensures automatic centering of vertical rods of different diameters, improving clamping stability and concentricity.

[0036] After the S4.1 master control module 203 confirms that the clamping component 5 has firmly clamped the L-shaped traffic light 8, it controls the drive wheel 102 of the frame component 1 to move in the opposite direction, so that the docking device 10 completely leaves the transport vehicle 7, avoiding interference with the construction caused by the movement of the transport vehicle.

[0037] The S4.2 main control module 203 coordinates the control of lifting component 1 2 and lifting component 2 3. First, it starts the lifting cylinder 205 to make a coarse adjustment with a large stroke, raising the L-shaped traffic light 8 to a certain height above the ground. Next, start the lifting motor 309 to drive the lifting screw 310 for fine adjustment of a small stroke, so that the L-shaped traffic light 8 can be precisely raised to a safe height that allows it to rotate horizontally without touching the ground.

[0038] The lifting motors 309 of lifting assembly 1 2 and lifting assembly 2 3 are synchronized by an encoder to ensure smooth lifting on both sides without tilting.

[0039] The S5.1 main control module 203 starts the rotary motor 402 of the rotary component 4, which drives the driven sprocket 406 through the active sprocket 403 and the transmission chain 404, thereby driving the rotary cylinder 405 to rotate smoothly in the rotary bearing 407.

[0040] The two telescopic electric cylinders 501 inside the S5.2 rotating cylinder 405 operate synchronously, driving the clamping assembly 5 to smoothly rotate the L-shaped traffic light 8 from a horizontal state to a vertical state.

[0041] During rotation, the central control module monitors the rotation angle and center of gravity changes in real time and dynamically fine-tunes the height of the lifting components to prevent the equipment from tipping over.

[0042] The S5.3 master control module 203 controls the movement of the chassis assembly 1, precisely moving the L-shaped traffic light 8 to directly above the required installation position.
